KN-6304 Coulometric Karl-Fischer Titration Tester

A knowledge of the water content of lubricating oils, additives, and similar products is important in the manufacturing, purchase, sale, or transfer of such petroleum products to help in predicting their quality and performance characteristics

KN-203 Volumetric Karl Fischer Moisture Titrator

although the volumetric KF titration can determine low levels of water，it is generally accepted that coumometric KF titrations are more accurate for routine determination of very low levels of water. as a general rule, if samples routinely contain water concentrations of 500Mg/kg or less,the coumometric tech should be considered.

KN-4049 Water Spray for Lubricating Grease

This tester is used to evaluate the ability of a grease to adhere to a metal surface when subjected to direct water spray. The results obtained from the use of this test method suggest correlation in operations involving direct water spray impingement such as steel mill roll neck bearing service. This test method is used for quality control and purchase specifications.

KN-1264 Water Washout Characteristics Of Lubricating Grease

This test method estimates the resistance of greases to water washout from ball bearings under conditions of the test. No correlation with field service has been established.

KN-942Z Greases Oxidation Stability apparatus

This apparatus measures the change in pressure resulting from consumption of oxygen by oxidation and gain in pressure due to formation of volatile oxidation by products. It predicts neither the stability of greases under dynamic service conditions, nor the stability of greases stored in containers for long periods, nor the stability of films of greases on bearings and motor parts. It should not be used to estimate the relative oxidation resistance of different grease types.

KN-4294 X-ray Fluorescence Sulfur Content Apparatus

The quality of many petroleum products is related to the amount of sulfur present. Knowledge of sulfur concentration is necessary for processing purposes. There are also regulations promulgated in federal, state, and local agencies that restrict the amount of sulfur present in some fuels

KN-972 Evaporation Loss for Lubricating Grease

The loss of volatile materials from greases and oils can adversely effect the original performance characteristics of a lubricant and therefore could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can also be considered contaminants in the environment in which the lubricant is to be used. Correlation between results from this test method and service performance has not been established.

KN-2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester

KN-2595 Lubricating Grease Wide Temperature Range Evaporation Loss Tester conforms to ASTM D2595 Standard Test Method for Evaporation Loss of Lubricating Greases Over Wide-Temperature Range. A weighed sample of grease in an evaporation cell is placed in a heating device maintained at the desired test temperature. Heated air is passed over the grease surface for 22h±0.1h. The loss in weight of the sample due to evaporation is determined.

KN-1743 Corrosion Preventive Properties of Lubricating Greases

New, cleaned, and lubricated bearings are run under a light thrust load for 60 6 3 s to distribute the lubricant in a pattern that might be found in service. The bearings are exposed to water, then stored for 48 6 0.5 h at 52 6 1°C (125 6 2°F) and 100 % relative humidity. After cleaning, the bearing cups are examined for evidence of corrosion

KN-566 Lubricating Grease Dropping Point Tester

the dropping point is the temperature at which the grease passes from a semisolid to a liquid state under the conditions of test.
